Wow, tempting! Unfortunately, my lens is below the bottom of the screen, and it looks like the lens shift max is the bottom of the screen.
I think you have more room to play than that. My Infocus SP8602 was supposed to be at the bottom or top of the screen. I had the lens about 13 inches below the screen. I didn't have any issues getting the image lined up properly. I also installed my friend's w6000 a couple of years ago. From memory, the lens is above the top of the screen by several inches.
The price is tempting. I'm trying to hold out till next fall before I buy another projector. If I bought one these it would be for 3D and general TV show viewing.
